不少在广告中声称可在南方各省推广的甜油桃品种,在南方许多地方均不能正常开花结果。主要原因有四:一是南方冷积温严重不足,无法满足果树冬季休眠的需冷量;二是花芽、幼果不耐高温,致使花芽败育或幼果凋零;三是果实的膨大速度跟不上南方春末夏初的气温回升速度,致使果实无法正常膨大,失去栽培的意义;四是不少育种单位在杂交育种时以兴津油桃为父、母本,致使所推品种含有大量的裂果基因,形成不了商品。福建龙岩位于台海西岸,与漳州仅一岭之隔,年平均气温20.1℃、年降雨量1450～2200mm,我公司能种成功的甜油桃,您还怕种不成功吗?
Many of the sweet nectarines claimed in advertisements that can be promoted in the southern provinces do not bloom in many places in the South. There are four main reasons: First, a serious shortage of cold accumulation in the south, fruit trees can not meet the need to sleep in winter cooling; Second, flower buds, young fruits are not resistant to high temperatures, resulting in flower buds or young fruit withered withered; Third, the fruit swollen with the speed Fourth, a lot of breeding units in the cross breeding Xingjin nectarine as the parent, the resulting variety is pushed by a large number of Fruit cracking genes, can not form a commodity. Fujian Longyan is located in the west bank of the Taiwan Strait, and Zhangzhou is only separated by a ridge, the annual average temperature of 20.1 ℃, the annual rainfall of 1450 ~ 2200mm, my company can plant a successful sweet nectar, you are afraid of species unsuccessful?
